The formula for finding the volume of a cone is v = 13πr2h. the volume of a cone is 300 cm3 and the height of the cone is 10 cm. what is the approximate radius of the cone?

Verified Answer :

Ckaranja

V=\(\frac{1}{3} \pi r^{2} h\)
V=300
h=10cm
300=\(\frac{1}{3} \pi r^{2}*10\)
\(r^{2} = \frac{300*3}{10 \pi } r^{2} = \frac{900}{31.42} r^{2} =28.65 r= \sqrt{28.65} r=5.352\)
